Peer-to-peer (P2P) poisoning company MediaDefender suffered an embarrassing leak this weekend, when almost 700MB of internal company e-mail was distributed on the Internet via BitTorrent. The e-mails reveal many aspects of MediaDefender's elaborate P2P disruption strategies, illuminate previously undisclosed details about the MiiVi scandal, and bring to light details regarding MediaDefender's collaboration with the New York Attorney General's office on a secret law enforcement project. We have been reviewing the data for days and will have multiple reports on the topic.

MediaDefender specializes in file-sharing mitigation—practices that disrupt and deter infringing uses of P2P file-sharing networks. Music labels and movie studios pay the company millions of dollars to temporarily impede the propagation of new releases in order to compel consumers to pursue legitimate commercial distribution channels. MediaDefender accomplishes this task by using its array of 2,000 servers and a 9GBps dedicated connection to propagate fake files and launch denial of service attacks against distributors.
